currently 12x CPU x86-64 Xeon E312xx and 32GB Ram, but that's way more than it needs. According to the current load i would say that 8x CPU and 16GB is enough, but since I'm moving the db to another box i will review the specs once i'm done with the new architecture. Also I haven't done much testing running big queries across the whole fleet, so not sure the impact this would have when i start to use it more actively
